IIS 8 Hosting Europe :: How to Fix Issue Coldfusion IIS 8 on Windows 2012

clock July 22, 2013 06:38 by author Scott

Are you getting the following error when configuring the IIS8 connector for CF10 on Windows Server 2012 or Windows 8?

"Version 8.0 is installed. Supported versions are 4.x, 5.x, 6.x, 7x"

We have some additional guidance that should help you work around it.

1) Please make sure that you are using correct Windows 2012 Server/Windows 8 supported ColdFusion 10 installer (The updated full ColdFusion 10 Installers)

MD5s of the full installer should be as follows:

For Win 64-bit MD5 --> ef74d583a8d069c7138a4ea8da9c5359

For Win 32-Bit MD5 --> ca9363a0a3817533436238b477b88792

2) You can opt to configure IIS 8 while installing or after installation.

     Installer has in-built support for IIS 8 on Win 8/Win 2012.

3) By all means install the latest CF10 updates, but do not apply updates older than Update 8. If you apply any of the older updates like update 7 or 6, you will likely see the following error while trying to run the IIS 8 web server connector:

"Version 8.0 is installed. Supported versions are 4.x, 5.x, 6.x, 7x" 

4) If all the above steps have been followed and if you are still getting the error, please verify that update 8 is installed properly by checking the log file under \cfusion\hf-updates\hf-10- 00008\Adobe_ColdFusion_10_Update_8*.log

And MD5  of the connector jar located at <CF10_Install_Home>\cfusion\runtime\lib\wsconfig.jar should be

     a) If you have applied Update 8 -> ba8f8c8bcd34c266faa0031107bbf948.

     b) If you have NOT applied any Updates -> 35cc2f630325506081f3b29d41e50c3c


European IIS 8 Hosting - Amsterdam :: Windows 2012 IIS 8 New Features

clock July 19, 2013 06:05 by author Scott

Internet Information Services (IIS) 8.0 Express is a free, simple and self-contained version of IIS that is optimized and available for developers. IIS 8.0 Express makes easy to use the most current version of websites tools like Visual Studio and WebMatrix. IIS 8.0 Express has all the core features of IIS as well as additional features for easy website development which includes:

- IIS 8.0 Express doesn't run as a service or require administrative privileges to perform most tasks.
- IIS 8.0 Express allows Multiple Users to work independently on the same computer.
- IIS 8.0 Express works well with ASP.NET and PHP applications.

IIS 8.0 is only available in Windows Server 2012 and Windows 8. It includes Application Initialization, centralized SSL certificate support, multi core scaling and also other new features.

Previously, we have discussed about new features in IIS 8. Now I will show more information about this new features.

1. FTP Logon Attempt Restrictions

This module ensures the security and manageability. Due to this feature you can now use greylisting and access patterns enabling you to smoothly and dynamically manage access for number of sites to the internet and FTP servers.

2) Improved CPU Throttling

In IIS8 there are kernel level changes to support real CPU throttling. There are two actions possible for sites that reach the CPU threshold. These are:

  • Throttling is based on the user and not specifically on the application pool. The throttle feature will keep the CPU for a particular worker process at the specified level.
  • Throttle under load will allow a site to use all possible CPU, while throttling the worker process if the server is under load. If you used WSRM (Windows System Resource Manager) in the past, you no longer need to do so.

3. Application Initialization Module

Priorly known as the application warm-up module which was used for a time, and now it is completely ready as Application Initialization Module. This allows loading sites and pages before the traffic arrives and handling of requests in a friendly and more smoother way while the application first loads. It is possible to set up home page or use URL rewrites.

4. SSL scalability

In previous versions of IIS each SSL (Secure Socket Layer) site required its own IP address, and since each certificate was loaded into the memory on the first visit to an SSL site, startup performance can be slow. In IIS8 the SSL certificate is easily scalable to thousands of secure sites per system because only the certificate that is needed is loaded. Additionally, also loading of large numbers of certificates is essentially improved.

5. SNI / SSL host header support

Using host headers and a shared IP address with SSL certificate has always been ambiguous. IIS8 now offers Server Name Indication (SNI) support through which many SSL sites can share the same IP. SNI is a pretty new feature which allows host headers to work with SSL. The most recent browsers are supporting SNI.

6. Use ASP.NET 3.5 and 4.5

IIS 8.0 on Windows Server 2012 runs ASP.NET applications on all .NET Framework versions supported on Windows Server 2012. This means ASP.NET applications can run on IIS 8.0 using either .NET Framework 3.5, or .NET Framework 4.5. IIS 8.0 hosts versions of the .NET Framework in different application pools, thus allowing multiple ASP.NET applications with different .NET Framework versions to run simultaneously on Windows Server 2012.

7. Web Sockets

Allows you to build more interactive and powerful web applications because of a continuous and bidirectional communication between the web browser and the web server. Web Sockets require Windows Server 2012 or higher versions.

8. Dynamic IP Restriction (DIPR)

With DIPR we can Customize IIS reply like Unauthorized (HTTP 401), Forbidden (HTTP 403), Not Found (HTTP 404), or Abort (IIS terminates the HTTP connection). Also we can allow or deny specific IP address or a range of IP addresses, even if they violate a dynamic restriction setting. We can block dynamic IPs based on the number of concurrent requests or the number of requests over a period of time.Finally it is a very useful feature for web servers behind firewall, because of the proxy mode property that enables IIS to cross checks the values in the X-Forwarded-For HTTP header. So it can verify the IP address of the client who initially made the request.

9. Multicore Scaling on NUMA hardware

Internet Information Services (IIS) on Windows Server 2012 supports Multicore Scalling on NUMA hardware and provides the optimal configuration for the IT administrators. Following options describes the different configuration options to achieve the best performance with IIS 8.0 on NUMA hardware.IIS supports following two ways of partitioning the workload:

  • Run multiple worker processes in one application pool: If you are using this mode, by default, the application pool is configured to run one worker process. For maximum performance, you should consider running the same number of worker processes as there are NUMA nodes, so that there is 1:1 affinity between the worker processes and NUMA nodes. This can be done by setting "Maximum Worker Processes" AppPool setting to 0. Due to this setting, IIS determines how many NUMA nodes are available on the hardware and starts the same number of worker processes.
  • Run multiple applications pools in single workload/site: In this configuration, the workload/site is divided into multiple application pools. For example, the site may contain several applications that are configured to run in separate application pools. Effectively, this configuration results in running multiple IIS worker processes for the workload/site and IIS intelligently distributes the processes for maximum performance.
